I have that I & T service manual that says that. I will look again tomorrow, but I did not see any shoulder. Do those bearings at the rear support come out?

Im not sure about the bearings, I will take a look in the books and see what I can find out. If I remember correctly on my G950, the ball bearing on the shaft is held in by a snap ring in the rear housing but not sure if the Jet Star series is the same. The shoulder on the shaft is almost non existant from what was on the 950. It was probably 1/16" to 1/8". I think what happens with them is the cage that houses the plates gets a little mushroomed and doesnt slide over the splines well. Mine was loose but didnt want to slide forward.

after straightening the lock washer and loosening the large nut locked by the washer, slide the whole clutch, except the inner hub and outer cage, foward until you can remove the cotter pin from the set screw & the set screw itself. Then pry the inner hub forward enough to remove the key from the shaft (remove it between the inner hub and the outer cage). To get the key out, you will have to move the inner hub forward as far as possible. Only after the key and the setscrew have been removed can you move the shaft rearward. Everything on the rear of the shaft will come out the rear of the tractor. The shaft is usually hard to move. I use a 24" pipe wrench on the rough part of the shaft near the front of the rearend case (ahead of the threads). Pull rearward on the wrench handle (to grip the shaft), then pry the wrench rearward with a large prybar against the front of the case. When sliding the shaft out, there are two brass thrust washers, one on each side of the PTO drive gear that you will need to catch if you don't want to hunt for them. If the marks you make on the shaft with the wrench prevent things from sliding off the shaft, I tap them with a hammer then clean them up after the shaft is out.
